[0023] like Figure 2 As shown, the automatic lifting platform mechanism 2 includes a base 21 and a lifting platform 22. A slider 23 is arranged on the lower surface of the base 21, and a slide groove adapted to the slider 23 is arranged on the frame. A first driving mechanism 26 is also arranged below the base 21, and the first driving mechanism 26 drives the base 21 to slide horizontally along the frame; a V-shaped support block 24 is arranged at each end of the upper surface of the lifting platform 22, and a bolt mounting hole is reserved on the V-shaped support block. The V-shaped support block 24 is fixed to the lifting platform 22 by bolts, and shaft workpieces are placed on the two V-shaped support blocks 24. A guide column 25 is arranged between the base 21 and the lifting platform 22. A second driving mechanism 27 is fixedly arranged on the lower surface of the base 21, and a telescopic rod of the second driving mechanism 27 is connected to the lifting platform 22, and the second driving mechanism 27 drives the lifting platform 22 to move up and down under the guidance of the guide column;

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, the automatic clamping mechanism 3 includes a spindle box 31 and a tailstock 32. The spindle in the spindle box 31 is driven to rotate by a motor 33. A three-jaw chuck 35 is installed at one end of the spindle. The tailstock 32 includes a top 37, a fixed base 38 and a first pneumatic device 39. The first pneumatic device 39 pushes the top 37 to cooperate with the three-jaw chuck 35 and the pneumatic clamp to realize automatic clamping of the workpiece.

[0025] like Figure 6 As shown, the detection mechanism 4 includes a laser detector 41, a lifting pneumatic mechanism 42 and a rotating cylinder 43. The rotating cylinder 43 is fixedly mounted on the frame. The lifting pneumatic mechanism 42 is arranged on the cylinder body of the rotating cylinder 43. The laser detector 41 is mounted on the other end of the lifting pneumatic mechanism 42 through a supporting rod 44. The cylinder body of the rotating cylinder 43 rotates, driving the lifting pneumatic mechanism 42 and the laser detector 41 to rotate. The lifting pneumatic mechanism 42 drives the laser detector 41 to move up and down.

[0026] The first driving mechanism 26 , the second driving mechanism 27 , the motor 33 , the pneumatic claw, the first pneumatic device 39 , the laser detector 41 , the lifting pneumatic mechanism 42 and the rotating cylinder 43 are all connected to a PLC controller (not shown in the figure), and the PLC controller is connected to a display 45 .

[0027] Furthermore, there are four guide posts 25, which are respectively arranged at the four corners of the base 21, so as to ensure that the lifting platform 22 is balanced in force and does not deflect.

[0028] Furthermore, the first driving mechanism 26, the second driving mechanism 27 and the first pneumatic device 39 are all cylinders. The lifting pneumatic mechanism 42 is also a cylinder. The air sources of the first driving mechanism 26, the second driving mechanism 27, the first pneumatic device 39, the lifting pneumatic mechanism 42 and the rotating cylinder 43 all come from the air compressor 5 arranged under the frame.

[0029] The shaft workpiece is placed on the V-shaped support block 24, and the PLC controller shares data with the shaft processing unit. The lifting height of the lifting platform 22 is adjusted according to the processing data of the shaft workpiece to complete the accurate positioning of the axis of the shaft workpiece and the center of the pneumatic clamping jaws. The first driving mechanism 26 on the right side below the base 21 controls the lifting platform 22 to move horizontally along the frame to send the shaft workpiece to the clamping position of the three-jaw chuck, and assist the three-jaw chuck and pneumatic clamping jaws to complete the clamping of the axial workpiece.

[0030] The automatic clamping mechanism 3 is mainly composed of a spindle box 31 and a tailstock 32. The spindle in the spindle box 31 is connected to the motor 33 through a transmission belt and is powered by the motor 33. The motor 33 rotates to drive the spindle 34 to rotate. A three-jaw chuck 35 is installed at one end of the spindle. A pneumatic clamp is set on the three-jaw chuck 35. The automatic clamping function of the pneumatic clamp can be realized through the second pneumatic device 36 at the rear; the tailstock 32 is composed of a top 37, a fixed base 38 and a first pneumatic device 39. The first pneumatic device 39 can push the top 37 to cooperate with the three-jaw chuck 35 and the pneumatic clamp to realize the automatic clamping function of the workpiece. The second pneumatic device 36 is also a cylinder, and the air source is provided by the air compressor 5. The second pneumatic device 36 is also connected to the PLC controller.

[0031] A laser detector 41 is installed at one end of the telescopic rod of the lifting pneumatic mechanism 42 of the detection mechanism 4 through a support rod 44. The support rod 44 is perpendicular to the lifting pneumatic mechanism 42. The laser detector 41 faces the shaft workpiece. The lifting pneumatic mechanism 42 can adjust the height of the laser detector 41 by lifting. The rotating cylinder 43 can rotate the lifting pneumatic mechanism 42 and the laser detector 41 90°. When placing the shaft workpiece on the lifting platform 22 and clamping it, the laser detector 41 rotates 90° to the side to prevent the shaft workpiece from damaging the laser detector 41. After the shaft workpiece is clamped, the rotating cylinder 43 rotates 90° to rotate the laser detector 41 to the top of the shaft workpiece. The laser detector 41 detects the radial runout of the shaft by radiating a laser beam.

[0032] During operation, the robot in the shaft production unit grabs the processed shaft workpiece and puts it onto the lifting platform 22. The PLC controller shares the processing data with the shaft production unit. The PLC controller controls the second drive mechanism 27 to drive the lifting platform 22 to rise and fall, and adjust the height of the lifting platform 22. After reaching the appropriate height, the lifting platform 22 moves toward the three-jaw chuck 35 through the first drive mechanism 26. The second pneumatic device 36 drives the pneumatic jaws on the three-jaw chuck to clamp the workpiece. At the same time, the first pneumatic device 39 of the tailstock 32 drives the top to extend and tighten the shaft workpiece. The second drive mechanism 27 drives the lifting platform 22 to descend and detach from the workpiece. The spindle of the automatic clamping mechanism 3 drives the workpiece to rotate slowly. The detection mechanism 4 rotates 90° to the top of the shaft workpiece. The laser detector 41 is used to detect the shaft end runout and feedback to the display 45.

[0033] The fully automatic shaft collaborative detection device disclosed in the utility model cooperates with the shaft processing automation assembly line in the mechanical manufacturing workshop and is used for external circle runout detection. The whole process includes automatic loading, detection, data output and other functions, avoiding manual detection, improving production efficiency and reducing the labor intensity of workers. It also has the following advantages:

[0034] 1. The device adopts a fully automated design, which can achieve the whole process without manual operation. It can complete the clamping, detection, output and other functions by itself, reducing labor costs.

[0035] 2. Except for the main axis, all movements of the device adopt pneumatic design, which can realize functions such as high-precision positioning of the workpiece, rapid response, and reliable structure.

[0036] 3. The device has strong expansion capability and can be combined with the shaft automation production unit to improve the shaft automation production line and realize fully automated production.

[0037] 4. The device uses laser detection, which has the characteristics of high precision, fast response, and non-contact measurement. It can transmit the inspection and measurement data to the LCD display in real time, which is convenient for monitoring the processing quality of shafts.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
